Coat
In smooth coats, the coat should be soft, close and glossy. Heavier coats with undercoats are acceptable. Coat placed well over body with ruff on the neck preferred and more scantier on head and ears. Hair on tail is preferred furry.
In long coats, the coat should be a soft texture, either flat or slightly wavy with an undercoat preferred. A thin coat that resembles bareness will disqualify the dog.
On the ears, the fur should be fringed. On the tail, the fur should be full and long like a plume. Feathering on feed and legs, pants on hind legs and large ruff on neck is desired and preferred. They should only be groomed to create a neat appearance.
Color
Any color is acceptable; the color may be solid, marked or splashed.
Gait
The Chihuahua should move swiftly with a firm, sturdy action, with good reach in front equal to the drive from the rear. From the rear, the hocks remain parallel to each other, and the foot fall of the rear legs follows directly behind that of the forelegs. The legs, both front and rear, will tend to converge slightly toward a central line of gravity as speed increases. The side view shows good, strong drive in the rear and plenty of reach in the front, with the head carried high. The topline should remain firm and the backline level as the dog moves.
Temperament
Alert, projecting the ‘terrier-like’ attributes of self importance, confidence and self reliance.

I enjoyed your story and your dogs are so cute. They are fun little critters, aren’t they! I had never had–or wanted–a Chi before. But last year was awful…I lost my 14 yr old Border Collie, and my best friend and my daughter ( age 49, both died with lung cancer 2 months apart. A neighbor hd a couple of Chi’s and just loved them. Well, she showed up at my door with ababy chihuahua, and said “I think you need this.” I said, Oh, no i don’t.” She said he needed a home badly. His family was splitting up & he wasn’t getting proper care. I have “sucker” imbedded in my forhead when it comes to animals in need. I took him to the vet 3 days later to have a check-up and get annual shots. Well, he weighed 2.2 lb and still had baby teeth. After having 2 Big dogs that lived a long time, this Chi was so tiny. I gave himm everything a puppy could ever want or need, and now about 1 1/2 yrs later, he weighs just under 6 lb and is PERFECT.ha Of course we totally fell in love with him. The neighbor was right. i needed him as much as he needed me.
